SUBMERGED HEATING DEVICE.

SPECIFICATION forming part of Letters Patent No. 391,297, dated October 16, 1,888.

Application [ilcd March l2, 1888.

To all whom it may concern:

Be it known that I, THOMAS GAsoaDEN, a citizen of the United States, residing at \Vater loo, in the county of Black Hawk and State of Iowa, haveinvented certain new and useful Improvements in Submerged Heating Devices, ot' which the following is a full, clear, and exact description, reference being had to the drawings accompanying this specification.

The invention relates to that class of devices used in heating water for stock or domestic purposes; and its object is to provide a heating device that may be used with equal facility in deep or shallow water. This and minor objects are attained by the construction illustrated in the accompanying drawings, wherc- 1n- Fignre 1 is a vertical diametrieal section or tank. Fig. 2 is a plan view ol" atank, float, and heater, and provided with openings to receive the tlanges of the smoke-flue 9, the feedchute 7, and air-passage G, as shown best in Fig. 1.

The heater comprises an outer shell or casing, 1, closed at the bottom and provided near the top with an outwardlyproiecting flange, 1g, from the outer edge of which rises a vertical wall, 1", carrying a top plate which is provided at proper points with openings for connection of a-smoke-tlue, 9, a feed opening or chute, 7, closed by a cover, 7, and air-openings closed by a cover, 8, which is fitted with a register, 10. Within this shell or casing, near the bottom, is secured a grate, f1, from the front of which rises a partition, 3, to separate the combustion-chamber5 above the grate from an air passage or chamber, 6, leading from the register 10 to the ash-pit 4, er space beneath the grate. Above the combustionehamber 5 is a top plate, 2, extending from the ange 1 to the partition 3 and forming, in connection with the top plate, 15, a nue-chamber, 5a, openings 2", 2, 12, and 13 communieating therewith from the combustionchamber. The opening 2L is arranged beneath the smoke-hue 9, and is provided with a sliding damper, 11, by means of which it may be closed to prevent the direct passage of the products ot' combustion and compel them to traverse a tortuous course through the open- Serial No. 267.048. (No model.)

ings 12 and 13, and thence to the smoketine through the liuc-chamber 5, formed by the partition 3, wall 1", and top plates, 2 and 15, ot' the combustion-chamber and easing, respeetively. The feedepening 7Lb consists of a Vertical wall extending from an opening, 2b, in the top plate, 2, of the combustion-chamber 5 to and through the top plate, 15, of the easing, as shown in Fig. 1, where it is fitted with a cover, 7, as hereinbefore stated.

The register 10 of the coverS affords facilities for admitting more or less air to the combustion-chamber 5 through air-passage 6 and the grate 4t, and by removing thc cover S access can be had to the aslrpit 4 for cleaning or other purposes.

To the top plate, 15, ofthe easing is secured a float, 111-, of proper size and capacity to sustain the weight of the heater charged with fuel, the ,outer projecting edge of said float being by preference provided at intervals with perforations or openings 16 of such size as to admit of stock drinking through them. The edges ofthe ioat extend beyond the sides of the outer easing of the heater, as shown, and preferably close to the sides of the tank or water-receptacle, thus presenting an eX- tended Heating surface and tending to prevent access of trash to the tank.

The heater is designed to be floated in a tank of proper size to heat the water to be consumed by stock, though it will be apparent that it may be used to boil water for scalding hogs or for domestic purposes, and that it may be used as an agricultural boiler in cooking food for stock.

In operation the heater is floated in a tank or other receptacle containing water or feed, and the fuel ignited. Should the draft be too strong, the register 10 on cover S can be closed more or less, or the damper 11 can be closed, thus shutting off the direct draft through the smoke-flue 9, and causing it to traverse a tortuons course through the openings 12 and 13, and thence through the {ine-chamber to the smoke-liuc. By this latter manipulation the radiation of the heater will be increased, as the heat from the ire will be less apt to escape through the smoke-ilue 9. To replenish the fuel, the cover 7 is removed, fuel fed in through the chute or opening 7 ,and the cover replaced.

IOO

Having thus described my invention, what I claim as new7 and desire to secure by Letters Patent, is-

1. In a water-heater, the combination of a watertight casing provided at its top with airinlet and smoke-discharge tlues and a feedchute, with a oat extending beyond the sides of said casing and provided with openings for the air-inlet and smoke-discharge fines and feed-chute, and with marginal openings located between the sides of the casing and eir- Oumferenee of the float, substantially as described.

2. The combination, substantially as described, of the outer easing, the grate and partition forming the air and combustion chambers, an opening in the top of the casing leading to the air-chamber, the plate 2, forming the top of the Combustion-chamber and bottom of the ilue-chamber and provided with Openings 2", 12, and 13, the damper arranged to close opening 2, the smoke-Hue, the register, and a feed-chute leading from the exterior of the easing through the fine-chamber to the combustion-chamber.

3. The combination, with a water-tank, of the casing, the grate, partition, and top plate, 2, forming air, iue, and combustion chambers, openings leading from the cOmbustion-chamber to the line-chamber, a damper to close one of said openings, a smoke-fine leading from the {ine-chamber above the damper to the exterior of the casing, a feed-opening leading from the exterior ot' the casing to the combustion-chamber, a register to control the admission of air to the air-chamber, and means to sustain the casing.

InV testimony that I claim` the foregoing as my own I have hereunto aixed my signature in presence of two witnesses.
